 * import {MiniTemlater} from 'miniTemplater'
 * let templateText = "Some text including {{thisTag}}"
 * let templateConfig = {thisTag: 'My Data'}
 * let renderedText = MiniTemlater(templateText, templateConfig)
 * console.log(renderedText)
 * // => "Some text including My Data"
 *
 * @param templateText Input text potentially containing the handlebars-style tags (eg. {{myTag}})
 * @param config Parse configuration containing the translate information (eg. {myTag: "My custom data})
